IMPROVEMENT IN INVALID ROCKING-CHAIRS.

Specification forming part of Letters Patent No. 216,582. dated J uno17, 1879; application filed November 11, 1878.

To all whom it may concern Be it known that I, CHARLES SUND UIsT, ofChattanooga, in the county of Hamilton, and in the State of Tennessee,have invented certain new and useful Improvements in Rockin g-Ohairs;and do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists in the.

construction and arrangement of areclining rocking-chair, as will behereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in which-Figure l is a side elevation of my improved reclining rocking-chair.Fig. 2 is a bottom View of the same. Fig. 3 is a longitudinal sectionthereof, and Fig. 4 is a detailed section of the side of the chair.

A represents the seat-frame of my chair, connected to and supported byrockers B, of any ordinary construction.

To the rear edge of the frame A is hinged the back B, which is sustainedpartially and thrown forward by means of a flat spring, (J, fastened tothe rear of the seat-frame, and bearing against the lower cross-bar ofthe back B.

To each side of the back B is pivoted a curved armrest, D, the forwardend of which has a thumb-screw, a, passing through it..

Each thumb-screw a passes through a slot, as, in the side of theseat-frame A, and enters a sliding block or nut, I), placed in a grooveor recess on the inner side of said seat-frame. By these means the backB can be adjusted and held at any angle by firmly fastening the forwardends of the arms D D to the seatframe by means of the screws a a.

Below the slot at in the side of the seatframe is a slot, y, extendingthe entire length of said side, and corresponding with a groove on theinner side thereof. In these grooves is placed a cross-bar, F, which canbe moved forward or backward, as required, and held in position bymeansof a thumbscrew, p, at one end.

To the cross-bar F is hinged a frame, G,

provided with an upholstered panel, H, which is hinged at its forwardend, and its rear end held at any elevation desired by means of a pawl,d, pivoted to the under side of the panel, and taking into notches e cin a bar of the frame G. The upholstered panel H can thus be adjusted toform, as it were, a continuation of the seat of the chair. The forwardend of the frame G is provided with short legs I I, with a railing, f,above the frame for a footrest. Near this end, to the under side of saidframe, are hinged two longer legs, J J, connected by a round, h, whichlegs may be thrown down, and thus bring the frame G to anearly-horizontal position, whereby the chair may be transformed into alounge when desired.

The legs I and J are all provided with rollers i, so that in whateverposition the footrest frame may be arranged the occupant of the chaircan rock back and forth, if desired.

The cross-bar F, with the frame G, can be moved backward and forward,'as required. When moved entirely back the railing f forms an ordinaryfoot-rcst.

The legs J are held in either position, either folded or thrown down, bymeans of buttons m or other suitable devices of similar nature.

Having thus fully described my invention, what I claim new, and desireto secure by Letters Patent, is-

1. The combination of the rocking seatframe A, with slots a: m in itssides, the hinged back B, spring 0, and pivoted arms D I), with thethumb-screws a and sliding mus I), substantially as and for the purposesherein set forth.

2. In combination with the rocking-chair frame A B, the slidingcross-bar F, hinged frame G, legs I, provided with rollers, andrailingf, substantially as and for the purposes herein set forth. i

3. In combination with a rocking-chair, the adjustable foot-rest frameG, provided with the adjustable panel H, stationary legs I, and foldinglegs J, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 10th day of June, 1878. K

CHARLES SUNDQUIST. [L. 8.]
